Yesterday the Nokia Lumia 900 was announced at the CES 2012. According to the press release, it's first of Nokia's Windows Phone-based range to feature high-speed LTE connectivity, suggesting that more LTE phones are coming from Nokia. It's coming exclusively to AT&T in the coming months in cyan and matte black. There was no word on the pricing and the availability of Nokia Lumia 900 for Europe and rest of the world.
The main differences of Nokia Lumia 900 compared to Lumia 800 are the 4.3" AMOLED ClearBlack Display, front facing camera, 1830 mAH battery and, of course, the 4G LTE network support. The design of Nokia Lumia 900 is very similar to the Lumia 800 and Nokia N9. The only difference seems to be the size, due the larger display of Lumia 900.
As for the content, there doesn't seem to be any major differences between the just announced Nokia Lumia 900 and the existing Lumia 800 and Lumia 710. However, video calling right out of the box was mentioned, but I haven't been able to find out more about it yet. I do presume that Skype is not out yet for Windows Phone. Another interesting detail was the Univision App. This will bring exclusive Spanish-language content to Lumia 900. I think this is a rather clever move, since sometimes I feel that there are more people who speak Spanish than English in U.S. and even more so in North America.
